That's true of every form of literature - each writer brings new things to it because each of us is an individual.

I love going to synagogue on Friday night and being swept in the melodies. Everyone seems more friendly and unburdened by the week and ready to be taken elsewhere.

I have a principle I often invoke in class: comfortable people don't grow. Good teachers need to engage in the paradox of making students feel comfortable and uncomfortable in equal measure.

In order to survive, the human race must defend itself.

I love space opera, and I believe that every sub-genre has potential no matter how old it is.

If people are not safe, they will not make themselves vulnerable. If they feel too comfortable, they can become complacent or lose their curiosity. They can become intellectually lazy about what matters most.

I don't read or write SF for cutting edge ideas; I read and write it for the storytelling, and every story is new. So have I brought anything new to it? Only in so far as no-one before has written about the characters I've invented in their particular situation.
